How to Turn a D Battery into a Mini Speaker

Build Your Own Portable Bluetooth Speaker inside a Battery
The video is a step-by-step guide on how to create a portable speaker using a D battery, a TP4056 charging module, and a CT14 Mini Stereo Amplifier Module Bluetooth-compatible module.
The video starts with an introduction to the components required and a brief explanation of their functions. The presenter then proceeds to demonstrate how to assemble the circuit by soldering the components together on a small circuit board.
After the circuit is assembled, the presenter shows how to connect a small speaker to the amplifier module and how to connect the battery to the charging module. The charging module ensures that the battery is charged efficiently and safely.
Once the circuit is assembled and the battery is connected, the presenter demonstrates how to turn on the speaker and connect it to a Bluetooth-enabled device. The sound quality of the speaker is also tested, and it is shown to produce clear and high-quality sound.
Throughout the video, the presenter provides helpful tips and advice on how to troubleshoot any problems that may arise during the assembly process. Overall, the video is an excellent tutorial for anyone interested in building their own portable speaker and learning more about electronics.
